Dr Warner was terrific! When I was having difficulty scheduling an appointment through the MGB online referral system, he immediately accommodated me and saw me within a week. I really appreciate him and his great staff. Highly recommend!!

I am very happy with what this provider gave me and any difference in what I have responded is really totally on me because I returned home very busy and I have not gotten around to completing all of the research that I want to do and get back. back to this provider. Thank you very much.

Dr. Warner made me feel comfortable. It was nice to be with a doctor who was so knowledgeable about my shoulder. I really appreciated him that day.


May 2025

I was referred to him from a friend and found him detailed, orientated on all the specifics of my injury and was able to give me a clear diagnosis of what should be done with options and referred me to a wonderful website that he developed that also gives me further information on my injury and we'll see what happens after the surgery in two weeks.

The best experience in a doctors office I have ever experienced. Seamless from start to finish.
